Australia's resource for control of worms, flies and lice in sheep,
and worms in goats

This month I'd like to welcome Maxine Murphy as our new ParaBoss News Editor. Maxine would be well known to many Queensland subscribers, as she ran the Qld DPI WormBuster Laboratory for many years until its recent closure. During this time Maxine provided worm control advice to producers and was involved in parasite management research. Maxine also edited sections of the WormBoss web site when it was rejuvenated a few years ago and she is on the ParaBoss Technical Committee.

From the Editor

Winter didn’t disappoint this year with falls of snow in the eastern states from Victoria and up onto the Granite Belt of Queensland.  In Queensland at least, these falls were touted as a once in a generation event. For sheep, it may not have been quite as exciting. Across to the west, weather conditions in the sheep raising regions were more typical, cold and wet with good pasture growth.

Not all worms ‘disappear’ when temperatures drop. Haemonchus (barber’s pole worm), for instance,  tends to find a quiet spot inside to wait out the winter, although a few can tough it out on the pasture, while others such as Trichostrongylus (scour worms) and Teladorsagia (small brown stomach worm) find the cooler conditions rather invigorating.

On a positive note, it is encouraging to see wool and lamb prices picking up.

Don't forget there is just till the end of July to check and re-save your ParaBoss News subscription to go into the draw for great prizes.

ParaBoss is also now on Facebook:

State outlooks for Month year

New South Wales

Weaners are wormy in various parts of NSW this winter and spring lambing ewes need to be assessed for worm burdens, including fluke, if your farm is in a ‘flukey’ region.  It’s also time to start planning the weaner paddock. Cattle weaners can also be wormy at this time of the year if the autumn drench was ineffective.

Conditions in the south west of the state were good over the winter, but the low level of soil moisture is of concern for good spring pasture growth.

In western Queensland the drought is the worst in 50 years. We welcome the return of a well-known and respected sheep advisor and we congratulate him on his new role as Program Manager (Agribusiness) Longreach Pastoral College. 

Western Australia

It’s been cold and wet with good pasture growth in the Esperance area. Use worm egg counts of lambs to gauge the level of worm control on your farm. If lambs are wormy then something is wrong.

>> full report

It’s been very cold with more frosts than usual, and it’s also dry.  Poor pasture growth has implications for poor body weights in lambing ewes increasing the risk of worm infestations and profoundly impacting on lactation.
